anyone have this model or know anything about it i was just wondering what the size the wheel bearing might be?

If you are not sure, just take the wheel and hub off. the bearings will fall out, and on the side of the bearing will be the part number that you can take to any parts store and match up. Be sure to check the races as well. If they need to be replaced, the part number should be in the same place on them as well. When I chance out the bearings, I always change out the races as well just to be sure. Also, don't forget new seals. Hope this helps. Good Luck!

By the way, how is your truck doing?

haha ya my truck is fine now thanks for asking they said that the computer in my tranny was all messed up but they paid for it didnt cost me a dime. thanks though. the reason i was wondering about the bearings without taking off the hub was beacuase i was going to go to a friends house and take care of the bearings so i didnt want to take it apart. just seeing if anyone had the same thing. but i can still take it apart just checking though.

I have a 1988 pro 17 and I think it is 1 1/16" (not positive, but I know its not 1")
